7 Studies have also demonstrated that balanced occlusion existing at denture delivery is often lost due to frequent post insertion adjustments, cold flow of acrylic and compression of mucoperiosteum under masticatory loads without patients complaining about it.
Electromyographic studies on patients with complete dentures showed reduced masticatory muscle activity with canine guidance and have shown better response compared to bilateral balanced occlusion.
6,9-12 The aim of this study was to compare patient satisfaction and masticatory efficiency of canine guidance over balanced occlusion when employed in complete dentures and this was carried out in a sample of Pakistani population.
group A for balanced occlusion group and group B for canine guided occlusion.
Beyli (1981) (4) in a survey of fractured dentures found that the most common cause of denture fracture is poor retention and lack of balanced occlusion.
Posterior teeth should be placed on the residual ridge and in balanced occlusion.
Group A patients were provided complete dentures with bilateral balanced occlusion concept.
After data analysis of the sample patients, results of the study showed that: There were 18 males (60%) and 12 females (40%) in group A with bilaterally balanced occlusion and a male to female ratio of 1.
4%) patients in bilaterally balanced occlusion and 16 (53.
Key Words: Lingualized occlusion, bilateral balanced occlusion, masticatory efficiency.
Both balanced occlusion and lingualized occlusion are recommended for complete dentures.
To date, it is unclear if patients notice differences in their ability to chew when they wear complete dentures manufactured with lingualized occlusal scheme when compared with dentures made with a bilateral balanced occlusion in Pakistan.
